The influential midfielder has made it clear that the Bavarians want to give their coach a fitting goodbye by winning the treble
The 68-year-old will make way for Pep Guardiola this summer and Schweinsteiger is eager to give the veteran coach a worthy send-off by clinching a historic treble.
"It will be our last match under Heynckes and that's another motivating factor. We want to give him a special send-off," Schweinsteiger was quoted as saying on the club's official website.
"The game at the Olympic Stadium is very, very important. I know what it's like to win there, so I'm highly motivated.
"It's always a wonderful evening in Berlin and the atmosphere and the stadium are something very special. We'll do whatever we can to win the cup.
"I'm too focused on Saturday’s match to be talking about the treble or anything else. We're all utterly determined to win this match."
Bayern clinched the Bundesliga title at the start of May before beating Borussia Dortmund in the Champions League final last Saturday, to leave them within touching distance of an incredible treble triumph.
